Find the smallest number that is divisible by 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10.
so it basicaly asks to find the least common multiple, so first we should try to factor everything.
1-1
2-2
3-3
4-2*2
5-5
6-2*3
7-7
8-2*2*2
9-3*3
10-2*5
So the number must have atleast 3 2's, 2 3's, a 5 and a 7
so from here (2^3)*(3^2)*5*7=8*6*5*7=1680
LCM(1,2,3,4,5,6,7,8,9,10) = 2,520
